Inflamed sinuses symptoms and conditions

I just got back from the doctor's office to examine the mysterious "dent" in my left buttocks. He didn't know what it was but I just googled the problem and confirmed it is from a Kenalog injection on 10/29/08. At Christmas time I just noticed rough looking skin but in the last couple of weeks I noticed the the "dent" was getting larger. I cannot believe the number of side effects for this drug. I was given the injection by my allergist for inflamed sinuses. What a price to pay huh? I only read one article that said her "dent" was filling in after a year and one half. Is there anything that will stop the growing of this "dent"?
